How Was Mount Kosciuszko Formed?

Mount Kosciuszko in Australia was formed between 355 to 490 million years ago during the Ordovician or Lower Devonian periods. Granite rocks were uplifted, folded and eroded over long periods of time. Mt. Kosciuszko rises 7,310 feet high and is part of the Australian Alps in Southeastern New South Wales. It's Australia's highest mainland peak. Unlike the Andes or Himalayas, Mt. Kosciuszko is eroding rather than uplifting.

Extensive glaciers formed around the mountain from 10,000 to 70,000 years ago. Large boulders on Mt. Kosciuszko continue to be worn down by water and ice. Glaciers formed Lake Cootapatamba on the southern side of the peak.

Snowmelt from the mountain feeds rivers and reservoirs responsible for the Snowy Mountains Hydro-electric Scheme. Surrounding peaks include Mts. Townsend, Twynam, North Ramshead and Carruthers. All these peaks are more than 7,000 feet tall. The region is known for winter sports such as skiing.

Mt. Kosciuszko is part of a national park bearing its name. The area was named a UNESCO Biosphere Reserve in 1977 due to its unusual alpine flora and fauna. The mountain was first climbed by Polish explorer Paul Strzelecki in 1840, after which he named the peak for Polish patriot Tadeusz Ko?ciuszko.
